Optional.
Determines whether to distinguish between lower case and upper
case. Set to False to ignore case differences. True by default.

min_match_strength

Optional. The
minimum fuzzy match score the two text strings must meet for itISFUZZYMATCH
to return True. Must be a number between 0 and 1.

0.67 by default.

For details on how the fuzzy
match score is determined, see
itFUZZYCOMPARE.

min_match_strength_type

Optional.
Determines how the fuzzy match score is determined. 1 by
default.

min_match_strength_type value

Result

1

The fuzzy match score is the
percent of the length of the match to the longer
input string's length.

If the input strings are
8 characters long and 12 characters long, and the match found is 6
characters long, the return value is 6/12 = 0.5.

If include_out_of_order_matches is True or omitted,
out of order matches may increase the fuzzy match score. See
include_out_of_order_matches.

If
min_match_strength_type is omitted, this is the default.

2

The fuzzy match score is the
percent of the length of the match to the shorter
input string's length.

If the input strings are
8 characters long and 12 characters long, and the match found is 6
characters long, the return value is 6/8 = 0.75.

If include_out_of_order_matches is True or omitted,
out of order matches may increase the fuzzy match score. See
include_out_of_order_matches.

3

The fuzzy match score is the
percent of the length of the match to the average
of the two input strings' lengths.

If the input
strings are 8 characters long and 12 characters long, and the match found is
6 characters long, the return value is 6/((8+12)/2) = 6/(20/2) = 6/10 = 0.6.

If include_out_of_order_matches is True or omitted,
out of order matches may increase the fuzzy match score. See
include_out_of_order_matches.

include_out_of_order_matches

Optional.
itISFUZZYMATCH makes one pass through the two original input strings,
finding matches. Then, by default, it makes more passes, assigning each
successive pass a lower fuzzy match score factor (see
out_of_order_match_strength), making as many passes as needed before there
are no more characters in common.

You may prefer
to restrict the search to a single pass only. To do so, set
include_out_of_order_matches to False.

Consider the input strings abbccee and eebbccf. The
first pass finds bbcc. The second pass finds ee. The second pass'
contribution to the final matching score is reduced by
out_of_order_match_strength. Then there are no remaining matching
characters.

True by default.

out_of_order_match_strength

Optional. If
specified, must be a number from 0 to 1.

0.75 by
default.

If include_out_of_order_matches is True or omitted,
itISFUZZYMATCH makes multiple passes searching for matching characters,
assigning each successive pass a lower fuzzy match score factor, making as
many passes as needed before there are no more characters in common.

To make each successive pass' match count less toward
the final score per matching character than the pass before it, each is
multiplied by out_of_order_match_strength, and out_of_order_match_strength
is itself multiplied by the previous pass' out_of_order_match_strength.

For example, if 5 passes are required before all
matching characters are found:

The first pass counts in full toward the final
score. out_of_order_match_strength is effectively 1 for the first pass.
If, for example, the first pass has a fuzzy match score of 0.6, then the
entire 0.6 counts toward the final score.

The second pass' score is reduced by multiplying it
by out_of_order_match_strength. If out_of_order_match_strength is 0.75
(the default), and if the second pass has a raw score of 0.2, then the
second pass contributes 0.2 x 0.75 = 0.15 to the final score.

The third pass' out_of_order_match_strength is
reduced by multiplying it by the previous pass'
out_of_order_match_strength, for an effective out_of_order_match_strength
of (by default) 0.75 x 0.75 = 0.5625. If the third pass has a raw score of
0.1, then the third pass contributes 0.1 x 0.5625 = 0.05625 to the final
score.
